Low oral and skin
toxicity. A flammable liquid. When heated
to decomposition it emits acrid smoke and
irritating fumes. | [Toxicity]
Both the acute oral LD50 value in rats and the acute dermal LD50 value in rabbits exceeded 5 g/kg (Russell, 1973) |
| Hazard Information | Back Directory | [Description]
4-(p-Methoxyphenyl)-2-butanone has an intensely sweet, floral,
fruity odor and a cherry-raspberry flavor at low concentrations.
May be prepared by condensing acetone with anisaldehyde to yield anisylidene acetone and subsequent hydrogenation in the presence
of Pd catalyst. | [Chemical Properties]
4-(p-Methoxyphenyl)-2-butanone has an intensely sweet, floral,fruity odor and cherry–raspberry flavor at low concentrations. | [Chemical Properties]
clear colourless to pale yellow liquid | [Occurrence]
Contained (approximately 53% level) in the odorous principle obtained by extraction and hydrolysis from aloe
wood (Aquilaria algallocha Roxb.) and in anise. | [Uses]
